My goldfish has been staying in one corner of the tank and does not leave often. It looks like its fins fins are fraying, or tearing and there are dark spots on its fins. What is wrong with my fish? What should I do?
It is in a 30 gallon tank kept at 76 degrees and I am using a Marineland Magniflow 160 canister filter.
